Wonder is defined by Thomas [Aquinas] in the Summa Theologiae [I-II, Q. 32, a. 8], as the desiderium sciendi, the desire for knowledge, active longin… - Josef Pieper

Now it is not our purpose here to condemn this world, from the standpoint of some "holiday-world" of philosophy. No words need be wasted on saying that this work-a-day world is very much with us, that in it the foundations of our physical existence are secured, without which no one can philosophize at all! Nevertheless, let us also recall, that among the voices which fill the workplace and the markets ("How do you get this or that item of daily existence?" "Where do you get that?" etc.) — in the midst of all these voices suddenly one calls above the rest: "Why is there anything at all, and not nothing?" — asking that age-old question, which Heidegger called the basic question of all metaphysics! Must we explicitly state how unfathomable this philosopher's question is, in comparison with that everyday world of needs and purposefulness? If such a question as this were asked, without introduction or interpretation, in the company of those people of efficiency and success, wouldn't the questioner be considered rather … mad?

If someone needs the "unusual" to be moved to astonishment, that person has lost the ability to respond rightly to the wondrous, the mirandum, of being. The hunger for the sensational, posing, as it may, in "bohemian garb," is an unmistakable sign of the loss of the true power of wonder, for a bourgeois-ized humanity.

To philosophize (we have already asked, What empowers the philosophical act to transcend the working-world?) — to philosophize means to take a step outside of the work-a-day world into the vis-à-vis de l'univers. It is a step which leads to a kind of "homeless"-ness: the stars are no roof over the head. It is a step, however, that constantly keeps open its own retreat, for the human being cannot live long in this way.
